Richard Richardson, a lawyer representing one of the families, held a news conference Tuesday, where he displayed racist commentary he claims is evidence of a kill list. One printout reads, “What is your focus for today?” with more words at the bottom reading “Lynch [N-Word],” said Richardson, who plans to use the examples in the lawsuit against the Fremont Union High School District and school administrators, writes CBS.

Officials did not “adequately protect” Black students, who were targeted by six to 10 unidentified male students of various races, in an incident last fall that only came to light following a recent mention in a student magazine, added Richardson.

The male students referred to themselves as “[n-word] kill spree masters,” notes the report, with the students putting the names of six to seven African-American students on the list. The lawsuit, which was filed on behalf of a female student’s family, said the male students threatened to “riddle her with bullets.”

District officials said administrators took disciplinary action against the students. And the Santa Clara County Sheriff’s office launched an investigation in September, with the district attorney’s office taking up the case for criminal prosecution, reports NBC Bay Area.
